如何解决C#：Opera 58.x 的问题 |操作驱动程序 2.42 | Selenium 3.141 - 无法访问 Opera

过去 10 年我一直从事产品开发和测试工作，几年前我接管了我们公司对我们的一种产品进行硒测试的研发工作。我正在更新我们的 C# 测试框架，该框架跨一系列浏览器测试我们产品的网络服务器功能。 PM 最近添加的浏览器之一是 Opera。目前，我们在我们的框架中使用以下版本控制：

Selenium WebDriver：V3.141.0.0 Selenium WebDriver.Support：V3.141.0.0 Operadriver_win64：V2.42 Opera 浏览器：58.0.3135.127

PM 指定我们必须确保我们为客户支持 Opera 58.x，因为这将在我们的下一个产品版本中记录给客户，因此很遗憾，我不得不针对此特定版本进行测试。

我在网上做了一些关于自动化 Opera 的广泛阅读。我从 GitHub 确定我需要为我的特定 58.x 版本的 Opera 安装operachromiumdriver v2.42。

I was a bit confused by this error because I can clearly see Opera started. So,I got looking at the logging for operadriver.exe:

当我使用 nunit 作为管理员运行上面的代码时，会依次发生以下 3 件事：

Operadriver.exe 控制台窗口启动
OperaSoftware.OperaWebBrowser.1610649940 控制台窗口启动
Opera.exe 实例启动

此时，nunit 提示本次测试出现如下错误： SystemTest_S7_1200.Communications._45WebServer._456_WebServer_Opera._45001_BasicFunctionality：设置：OpenQA.Selenium.WebDriverException：未知错误：Opera 无法启动：崩溃（Opera 无法访问）（从 chrome 位置 C:\Users\System Test\AppData\Local\Programs\Opera\58.0.3135.127\opera.exe 开始的进程不再运行，因此 OperaDriver 假设 Opera 已崩溃。）（驱动程序信息：OperaDriver=2.42.3135 (O58)，平台=Windows NT 10.0.17763 x86_64）

在 OperaSoftware.OperaWebBrowser 控制台中，记录了以下内容：

<head>
</head>
<body>
<table border='2' cellpadding='20' align='center'>
    <tbody>
    <tr>
        <td class="switch">1</td>
        <td class="switch">2</td>
        <td class="switch">3</td>
    </tr>
    </tbody>
</table>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js">
</script>
<script type="text/javascript">
    $('\.switch').click(function() {
        $(this).toggleClass('highlight');
        $(this).click(function() {
            $(this).toggleClass('highlight2');
        })
        $(this).click(function() {
            $(this).toggleClass('switch');
        })
    })
</script>
<style>
    .highlight {
        background-color: #ffff00;
    }
    .highlight2 {
        background-color: red;
    }
</style>
</body>

我知道我真的很接近让它工作......我认为这里的障碍是 DevTools HTTP 请求在多次尝试时失败，最终导致 InitSession 失败，因为它无法到达/附加到歌剧。

我的问题……我在这里遗漏了什么？对于我们测试的其他浏览器，如 Chrome、IE11、FF 等，启动 webdriver 并附加到浏览器实例一点也不难。恐怕我错过的任何东西都是显而易见的，而我只是没有看到。当然，根据我在网上的研究，在使用 Opera 进行测试时，我没有看到任何明确和明确的内容。被绑定到特定版本使这个问题更像是一个障碍。非常感谢任何输入。
